I plan to use a class D integrated, an april musis aura note 2 that has a B&O icepower amp that is 125/250 watts 8/4 ohm and has a good cd player,fm tuner and a dac that sounds graet to me. I ordered some red M4TMs and plan to pair them.
I used the April Music with my previous Klipsch Forte 2s that had titanium mid and high diaphrams and custom ALK crossovers and it was always very smooth,
It also drives my current Dynaudio Focus 160 s with ease and they arent exactly ticklish if ya know what im sayin.
Ive had four class d amps and they just keep getting better very quickly now like DACs are.
The little April sounds as good as the Revox B150 I still have around and that thing is CLEAN and smooth class A/B,
I can hear no reason a good class D would dissappoint you.Ncores,Ice,and a few others are here now,not catching up. The little 3116 chip amp I nused with a little tube pre was a smack in the face for what you can expect for your hard earned dollar.I believe class d with a tube pre(ala rogue sphinx and the like) is going to be great for us working class slobs that love music,
Good luck and enjoy the hunt
